Abstract
Based on first-principles calculation framework, the surface model, anodic dissolution , cathodic oxygen absorption reaction, and other related electrochemical corrosion models of Fe-Ce system were constructed, and the influencing mechanism Ce doping on the corrosion resistance of Fe-Ce system in the Cl medium environment was analyzed. The results show that Ce doping on the first surface and subsurface inhibits the ionization of Fe atoms and greatly promotes the repassivation process of Fe matrix. Ce doping on the first layer is conducive to preventing the detachment of surface Fe atoms from Fe matrix and delaying the occurrence of corrosion. Ce atoms in the subsurface effectively increase the difficulty of Fe…
